For the last three completed school years, Ohio has administered three different standardized tests to its school children. As a result, the results for schools and districts vary greatly.
In an attempt to accommodate these sometimes wild grade fluctuations, Know Your Charter has averaged all state report card grades over the last three years. As a result, some grades may be listed with pluses and minuses, depending on how the average worked out on a traditional four-point grading scale. State report card grades do not include pluses or minuses.
All data was taken from 2016-2017 school year data released by the Ohio Department of Education. Some teacher data is from 2015-2016.
